Chapter XIII: Preface (13)

_T. cordifolia_ grows to the height of 9in. to 12in.; the flowers are composed of a calyx (five-parted) and five petals, which are entire, evenly set in the calyx. The ten stamens are prominent; each flower has a stout pedicel, which holds out the pretty white blossom in a nearly horizontal way. There is nothing of a bell-shape character about the flower, as in its nearest relative the Mitella. The flower stem is erect and round, being evenly furnished with flowers, for a length of 4in. to 6in.; the flowers are very lasting. The leaves are heart-shaped, acutely lobed, denticulate, slightly wrinkled, hairy on both sides, and more or less spotted or splashed with brown spots on the main ribs; the leaf stalks are long, and carry the foliage gracefully. The whole plant has a neat habit, and, when in vigorous health, sends out surface creepers.

It enjoys moist quarters and slight shade, though it is grown as seen in the drawing in an exposed part. The soil is good, but otherwise there is nothing special about its culture. If this little spring flower can be made more known, it will be sure to be more widely cultivated; for covering the bare parts of lawn shrubberies it would form a pleasing subject, and might be mixed with the scarlet ourisia and the finer sorts of myosotis; these would make an excellent blend, all flowering together, and lasting for a long time, besides being suitable otherwise for such shady positions. When increase is desired strong plants may be divided at any time, soon after flowering being the best; if the season be dry, the young stock should be shaded by a leafy branch and kept well watered.

Flowering period, May and June.

Trientalis Europæa.

EUROPEAN WINTERGREEN, or STAR-FLOWER; _Nat. Ord._ PRIMULACEÆ.

Some may say, "Why, this is a common British plant;" and so it is in some parts, but for all that there are many who have never seen it. In no way does the mention here of this lovely little flower need an apology: the best possible reasons for growing and recommending it are in the facts that it is very beautiful and greatly admired (see Fig. 103).

(Plant, one-third natural size; blossom, full size.)]

The flowers, which are ¾in. across, are salver-shaped, pure white, excepting for a day or two when newly opened, then they are stained with a soft pink; the calyx has eight handsome light green, shining, awl-shaped sepals; the corolla has five to nine petals, equal in size, flatly and evenly arranged, their pointed tips forming the star-like appearance from which the flower takes one of its common names; the flower stalks are exceedingly fine--thready--but firm, from 1in. to 3in. long, and each carries but one flower; they issue from the axils of the leaves, which are arranged in whorls of five or seven, and nearly as many blossoms will be produced from the whorl, but seldom more than one, and hardly ever more than two, flowers will be open together, when they occupy the central position of the foliage, which gives the plant an elegant appearance. The leaves are of a pale green colour, sometimes a little bronzed at the tips, veined, entire, bald, lance-shaped, and, as before hinted, verticillate; they vary much in size, being from 1in. to 3in. long and ½in. to 1in. broad. The stems are round, reddish, slender, and naked, with the exception of two or three minute round leaves, borne distantly apart; the stems, too, like the leaves, vary in length; sometimes they grow 8in., while others equally floriferous are not above 3in. high; the root is creeping, and somewhat tuberous. A colony of this plant has the appearance of a miniature group of palms, bedecked with glistening stars at the flowering time, and it is one of the most durable flowers I know; so persistent, indeed, are they, that botanical descriptions make mention of it.

In a cut state they equal either violets or snowdrops, from the beautiful combination of flowers and foliage, and it is a pity that it is not grown in sufficient quantities for cutting purposes. Its culture is very easy, but to do it well it may be said to require special treatment; in its wild state it runs freely, and the specimens are not nearly so fine as they may be had under cultivation with proper treatment. It should have moist quarters, a little shade, light vegetable soil, and confinement at the roots. I ought, perhaps, to explain the last-mentioned condition. It would appear that if the quick-spreading roots are allowed to ramble, the top growths are not only straggling, but weak and unfruitful. To confine its roots, therefore, not only causes it to grow in compact groups, but in every way improves its appearance; it may be done by planting it in a large seed pan, 15in. across, and 4in. or 6in. deep. Let it be well drained; over the drainage place a layer of lumpy peat, on which arrange another of roots, and fill up with leaf soil and peat mixed with sand; this may be done any time from September to February; the pan may then be plunged in a suitable position, so as to just cover the rim from sight, and so do away with artificial appearances; but if it is sunk too deep, the roots will go over the rim and all the labour will be lost. So charming is this plant when so grown, that it is worth all the care. A well-known botanist saw such a pan last spring, and he could hardly believe it to be our native species. Pans at two years old are lovely masses, and very suitable for taking as grown for table decoration. The outer sides of the pans should be banked down to the tray with damp moss, which could be pricked in with any soft-coloured flowers, as dog roses, pinks or forget-me-nots.

I will only add that, unless the root confinement is effected either in the above or some other way, according to my experience, the plant will never present a creditable appearance as a cultivated specimen; at the same time, this somewhat troublesome mode of planting it is not in proportion to the pleasure it will afford and certainly ought not to prevent its introduction into every garden.

Flowering period, May and June.

Trillium Erectum.

ERECT WOOD-LILY; _Nat. Ord._ MELANTHACEÆ.

(One-half natural size.)]

A hardy, tuberous perennial, from North America, whence most, perhaps all, the species of this genus are imported. The peculiar form of the plants gives rise to the generic name. A flowering specimen has on one stem three leaves, three sepals, and three petals; the specific name is in reference to the more erect habit of this species compared with others. Of _T. erectum_ there are several varieties, having different-coloured flowers; the specimens from which the drawing (Fig. 104) was taken have rich brown or dark maroon flowers. Little groups have a rather quaint look, they being very formal, the flowers curiously placed, and of unusual colour. The flowers are fully 2in. across, or much more, if the petals did not reflex almost their whole length. The sepals of the calyx are exactly alternate with the petals, and remain erect, giving the flower a characteristic quality; and, let me add, they are far more pleasing to the eye than to the sense of smell. The leaves are arranged in threes on the main stem, and that number constitutes the entire foliage of the plant; they are stalkless, oval, but pointed, entire, smooth, and of a shining dark green colour. The specimens from which the illustration was made are 5in. to 6in. high, but their height differs very much with the positions in which they are grown, shade and moisture inducing taller growths. The roots, which are tuberous, are of unusual form--soft swollen root-stocks may be more descriptive of them. Trilliums are now in much favour, and their quiet beauty is likely to create a genuine love for them. Moreover, the different species are distinct, and if grown in cool, shady quarters, their flowers remain in good form and colour for a long time. They are seen to most advantage in a subdued light, as under the shade of rather tall but not too thickly grown trees. They require vegetable soil, no matter how light it may be, provided it can be maintained in a moist state, the latter condition being indispensable. Trilliums are capable of taking a good share towards supplying shade-loving subjects. How finely they would mix with anemones, violets, _Paris quadrifolia_, hellebores, and such like flowers! Colonies of these, planted so as to carpet small openings in shrubberies, would be a clear gain in several ways to our gardens; to many they would be a new feature; more showy flowers would not have to be given up for such an arrangement, but, on the other hand, both would be more enjoyed by the contrast. Trilliums increase slowly; propagation may be carried out by the division of the roots of healthy plants.

Flowering period, May and June.

Triteleia Uniflora.

_Sometimes called_ MILLA UNIFLORA; ONE-FLOWERED TRITELEIA, _or_ SPRING STAR FLOWER; _Nat. Ord._ LILIACEÆ.

This is a favourite flower, and in some soils increases very fast; it is the commonest species of the very limited genus to which it belongs; was brought from South America only so recently as 1836, and it is already extensively grown in this country, and as a trade article is very cheap indeed, thanks to its intrinsic worth. Though small, its star-like form gives it a lively and effective appearance in the borders. It is much used by the Americans as a window and greenhouse plant, notwithstanding that it is a wild flower with them, and its pretty shape and lovely hues render it eligible for such uses, but on account of the esteem in which is held the odour of garlic, I should not like to recommend it for such close associations. The flower in shape is, as the generic name implies, like the Trillium, formed of three, or rather threes; the divisions are arranged in threes, or triangularly; the two triangles, being crossed, give the flower a geometrical and star-like effect. The flowers, which are 1in. to 2in. across, are borne on slender stems, 4in. to 6in. long. They are nearly white, but have various tints, bluish reflections, with a line of blue in each petal. The leaves resemble those of the snowdrop when overgrown and turning flabby, and have a somewhat untidy and sprawling habit; they are abundantly produced from the rather small cocoon-shaped bulbs. On the whole, the plant is very ornamental when in flower, and the bloom is produced more or less for many weeks; at any rate, it is an early flower, and if it cannot be used indoors it should be extensively planted amongst border subjects, than which there are few more hardy or reliable. Propagated by divisions of the crowded bulbs every other year, during late summer.

(One-fourth natural size.)]

_T. u. lilacina_ (the Lilac-coloured Star Flower) is a most handsome variety, having, as implied by the name, a richly coloured flower. I am indebted to a lady for roots and flowers recently sent me; so far as I know, it is not yet generally distributed. It is very distinct from the type in having smaller parts throughout, and a more highly coloured bloom, with the outer surface of the shining tube of a darker or brownish-green colour. I have seen a mauve coloured form, but this is much more pronounced and effective. The chief recommendation of this otherwise desirable flower, to my thinking, is its rich, new-mown hay scent; in this it differs much from the parent form.

Flowering period, March to May.

Tritoma Uvaria.

GREAT TRITOMA; _Common Names_, FLAME-FLOWER, RED-HOT POKER; _Nat. Ord._ LILIACEÆ-HEMERO-CALLIDEÆ.

This is one of our finest late-flowering plants; it has, moreover, a tropical appearance, which renders it very attractive. It is fast becoming popular, though as yet it is not very often seen in private gardens; it comes from the Cape of Good Hope, its year of introduction being 1707. In this climate, when planted in well-exposed situations and in sandy loam, it proves hardy but herbaceous; if protected it is evergreen; and I ought to add that if it is planted in clay soil, or where the drainage is defective, it will be killed by a severe winter; but when such simple precautions as are here indicated will conduce to the salvation of a somewhat doubtful plant, it may be fairly termed hardy. According to my experience during severe winters, plants in wet stiff loam were all killed, but others of the same stock, in light sandy earth, did not suffer in the least. I have also made similar observations outside my own garden.

The stout scapes or stems sometimes reach a height of 4ft., and are topped with long or cocoon-shaped spikes of orange and red flowers; the flowers are tubular and small, closely arranged, and drooping; each will be about an inch long, and the spikes 6in. to 8in. long. The leaves are narrow, 2ft. to 3ft. long, keeled, channelled, and rough on the edges, of a dark green colour and prostrate habit. Either amongst trees or in more conspicuous positions this flower proves very effective, whilst in lines it is simply dazzling; when grown in quantity it may be cut for indoor decoration, than which few large flowers are more telling.

Cultural hints have already been given in speaking of its hardiness, but I may add that where the soil is naturally light and dry a liberal dressing of well-rotted manure may be dug in with great benefit to the flowers. It is readily propagated by division of the roots every third year; the young stock should be put in rows, the earth having been deeply stirred and well broken; this may be done in late autumn or spring--if the former, a top dressing of leaves will assist root action.

This bold and brilliant flower appears in September, and is produced in numbers more or less to the end of the year, provided the season does not set in very severe.

Tropæolum Tuberosum.

TUBEROUS TROPÆOLUM; _Nat. Ord._ TROPÆOLACEÆ.

All the species of this genus are highly decorative garden subjects, including the annual varieties, and otherwise they are interesting. They are known by various names, as Trophy-plant, Indian Cress, and Nasturtium, though the latter is only applicable strictly to plants of another order. The plant under notice is a climber, herbaceous and perennial, having tuberous roots, whence its specific name; they much resemble small potatoes, and are eaten in Peru, the native country of the plant. It has not long been grown in this country, the date of its introduction being 1836; it is not often seen, which may be in part owing to the fact of its being considered tender in this climate. But let me at once state that under favourable conditions, and such as may easily be afforded in any garden, it proves hardy. As a matter of fact, I wintered it in 1880-1, and also in 1881-2, which latter does not signify much, as it proved so mild; but it must be admitted that the first-mentioned winter would be a fair test season. The position was very dry, viz., on the top of a small bank of earth, against a south wall; the soil was sandy loam, and it was overgrown with ivy, the leaves of which would doubtless keep out many degrees of cold, as also would the dryness of the soil; another point in favour of my specimen proving hardy, would be the fact of its exposure to the sun, by which the tubers would be well and duly ripened. It is one of the handsomest trailers or climbers I know for the herbaceous garden; a free grower, very floriferous, bright, distinct, and having a charming habit. The illustration (Fig. 106) can give no idea of the fine colours of its flowers, or richly glaucous foliage. One specimen in my garden has been much admired, thanks to nothing but its own habit and form; under a west wall, sheltered from the strong winds, it grows near some _Lilium auratum_; after outgrowing the lengths of the stems, and having set off to advantage the lily bloom, it caught by its tendril-like shoots an apricot tree on the wall, and then reached the top, being furnished with bloom its whole length. The flowers are orange and scarlet, inclining to crimson; they are produced singly on long red stalks, which spring from the axils of the leaves; the orange petals are small and overlapping, being compactly enclosed in the scarlet calyx; the spur, which is also of the same colour, is thick and long, imparting a pear-like form to the whole flower, which, however, is not more than 1½in. long. The leaves are nearly round in outline, sub-peltate, five, but sometimes only three-lobed; lobes entire, sometimes notched, smooth and glaucous; the leaf-stalks are long and bent, and act as tendrils. The plant makes rapid growth, the stems going out in all directions, some trailing on the ground.

It is a good subject for the drier parts of rockwork, where a twiggy branch should be secured, which it will soon cover. It is also fine for lattice work, or it may be grown where it can appropriate the dried stems of lupine and larkspurs. For all such situations it is not only showy, but beautiful. The flowered sprays are effective in a cut state, especially by gaslight; they come in for drooping or twining purposes, and last a long time in water.

(One-fifth natural size.)]

If grown as a tender plant its treatment is as simple as can be; the tubers may be planted in early spring in any desired situation, and when the frosts at the end of the season have cut down the foliage, the tubers may be taken up and stored in sand; but if it is intended to winter it out the situation should be chosen for its dryness, and the soil should be of a sandy nature, in which the tubers ought to be placed 5in. or 6in. deep. It is self-propagating, the tubers being numerously produced; and like "potato sets," the larger ones may be cut in pieces; if, however, numbers are not the object they are better left uncut. Caterpillars are fond of this plant; at the first sight of an eaten leaf, they should be looked for and destroyed.

It begins to flower in the latter part of summer, continuing until stopped by frosts.

Umbilicus Chrysanthus.

_Nat. Ord._ CRASSULACEÆ.

(One-half natural size.)]

This is a very pretty and distinct subject, and never fails to flower very late in the year. It is a plant having the appearance of being tender, and is not often seen growing fully exposed in the garden; it is, however, perfectly hardy, enduring any amount of cold; it suffers more from wet. It is also evergreen. Its soft dull or greyish-green rosettes are in marked contrast with the rigid and shining sempervivums, in the company of which it is frequently placed. It is an alpine subject, and comes from the mountains of Asiatic Turkey, being also found more west. Not only is it interesting, but its pretty form and habit are qualities which render it very useful in a garden, more especially for dry parts, such as old walls and rockwork.

It grows 6in. high, the older rosettes elongate and form leafy flower stalks, which are topped by drooping panicles of flowers, somewhat bell shaped; each flower is ¾in. long, of a yellowish white colour; the petals are finely pointed, and well supported by a fleshy calyx; the bloom is slowly developed and very enduring, even when the worst weather prevails. The leaves are arranged in flat rosette form (the rosettes from 1in. to 2in. across), lower leaves spathulate, those near the centre more oval.

All are fleshy, covered with short hairs, and somewhat clammy to the touch. Its habit is neat, and it adorns such situations as otherwise suit it, viz., banks or risen beds, and such other positions as have already been named.

Its culture is easy, but it ought to have the compost it most enjoys--peat and grit--and it should be sheltered from the strong winds, otherwise its top-heavy flower stalks will be laid prostrate. When it once finds a happy home it increases fast; the thick stalks are procumbent and emit roots. These may either be left to form large specimens or be taken off during the growing season for stock. Excessive wet is its greatest enemy. For such subjects, the wire and glass shelters are not only a remedy, but very handy.

Flowering period, summer, until stopped by frosts.

Vaccinium Vitis-Idæa.

RED WHORTLE-BERRY; _sometimes called_ COW-BERRY; _Nat. Ord._ VACCINACEÆ.

Although a native evergreen, and in some parts occurring extensively, it proves to be both decorative and useful as a garden subject; as a neat evergreen it is worthy of a place, especially when it is not to be found near in a wild state. It is seldom seen without either its waxy and pink-tinted white flowers or its bright clusters of red berries, but in October it carries both, which, together with the fine condition of the foliage, renders the shrub most attractive. It grows 6in. to 9in. high under cultivation.

In form the flowers somewhat resemble the lily of the valley, but they are closely set in the stems and partly hidden, owing to the shortness and drooping character of the racemes; not only are the flowers pleasingly tinted, but they exhale a full and spicy odour; the buds, too, are tinted with a lively pink colour on their sunny sides. The berries are quickly developed, being nearly the size of the holly berry, but a more bright red. The leaves are stout, shining, and leathery, and ofttimes pleasingly bronzed. They are over ½in. long and egg-shaped, being bent backwards. The stems are furnished with short hairs, are much branched, and densely foliaged. This compact-growing shrub would make a capital edging, provided it was well grown in vegetable soil. It would go well with _Erica carnea_ to form a double line, either to a shrubbery or permanent beds of dwarf flowering trees. Now that berries are so much used for wearing about the person and for indoor decoration, those of this shrub may become useful. A dishful of sprigs in October proves pleasant both to the sight and smell, the flowers and fruit being charmingly blended.

(Natural size.)]

_V. v.-i. major_ is a variety which is simply larger in all its parts; it is, however, rather more bronzed in the foliage. I daresay by many it would be preferred to the typical form, both for its robust and decorative qualities. It is nearly twice the size of the type.

As may be inferred, both from the order to which this shrub belongs and the localities where it occurs in its wild state, a peaty or vegetable soil will be required. I find the species grow most freely in a mixture of leaf soil and sand, the position being moist but exposed. It does not object to a little shade, but then its useful berries are neither so numerously produced nor so well coloured.

It is easily propagated by division at almost any time.

Flowering period, May to October.

Veronica Gentianoides.

_Syn._ V. GENTIANIFOLIA; GENTIAN-LEAVED SPEEDWELL; _Nat. Ord._ SCROPHULARIACEÆ.

This is a distinct and pleasing species, viewed as a garden plant. It is very hardy, and one of the herbaceous kinds; it has been grown in English gardens nearly 150 years, and came originally from the Levant. It is pretty widely used, but it deserves a place in every garden; not only are its tall spikes of flowers effective during their season, but the foliage, compared with other Veronicas, is of a bright and plump character. The newly-formed tufts, which are somewhat rosette-shaped, have a fresh appearance throughout the winter, it being one of the few herbaceous subjects in which the signs of life are so visible in this climate.

The flowers are small-½in. in diameter--numerously produced on spikes 18in. high. They are blue, striped with light and dark shades; both calyx and corolla, as common to the genus, are four-parted, petals of uneven size. The flower spikes are finely developed, the flowers and buds occupying 12in. of their length, and tapering off to a point which bends gracefully. The buds are not less pretty than the flowers, resembling as they do turquoise in a deep setting of the calyx. The leaves are smooth, shining, and of much substance, 3in. to 6in. long, and 1in. to 2in. broad, lance-shaped, serrated, and sheathing. They are of a somewhat clustered arrangement close to the ground. Good pieces of this plant, 1ft. to 2ft. across, are very effective, and flower for a good while.

The rich and graceful spikes are of great value for vase decoration, one or two sufficing in connection with other suitable flowers.

There is a lovely variety of this species called _V. g. variegata_; in shape and habit it resembles the type though scarcely as vigorous, but not at all "miffy." The leaves are richly coloured pale green, white, and pink; and the flowers, as seldom occurs in variegated forms, are larger and more handsome than in the parent; in all respects, it is as useful, and, for forming an edging, perhaps more suitable than the common form.

Both kinds like a good fat loam and a moist situation; they may be grown either in borders or on rockwork, but specimens on the latter compare poorly with those grown otherwise; either they are too dry, or the soil gets washed from them, so that the new roots, which strike down from the surface-creeping stems, do not find the needful nourishment. Their increase is easily effected by division of the rooted stems any time after they have done flowering. If the season is droughty, they should be well watered.

Flowering period, May to July.

Veronica Pinguifolia.

FAT-LEAVED SPEEDWELL; _Nat. Ord._ SCROPHULARIACEÆ.

This is a rather uncommon species, being of the shrubby section, but unlike many of its relative kinds, it is perfectly hardy, also evergreen and very dwarf; a specimen three or four years old is but a diminutive bush, 18in. through and 8in. high. The habit is dense, the main or old branches are prostrate, the younger wood being erect and full of very short side shoots.

The flowers are produced on the new wood; the chubby flower-spikes issue from the axils of the leaves near the leading shoot; in some cases there are three, in others four, but more often two. Each flower spike has a short, stout, round stem, nearly an inch long, and the part furnished with buds is nearly as long again. At this stage (just before they begin to open) the buds are rice-shaped, snow white, waxy, and arranged cone form. They are, moreover, charmingly intersected with the pale green sepals in their undeveloped stage. The little bunches of buds are simply exquisite. The flowers are small, pure white, waxy, and twisted in the petals. The two filaments are longer than the petals, having rather large anthers, which are bright purple. This pleasing feature, together with the young shoots in the midst of the blossoms, which have small stout glaucous leaves tipped with yellow--nearly golden--give the clusters a bouquet-like appearance. The leaves are small--little more than half an inch long--and ovate, slightly cupped, stem-clasping, and opposite. They are a pale glaucous hue, and closely grown on the stems; they greatly add to the rich effect of the flowers.

This shrub is a most fitting subject for rockwork, and it would also make an edging of rare beauty, which, if well grown, no one could but admire. It seems to enjoy loam and leaf soil in a moist but sunny situation. It may be propagated by cuttings, taken with a part of the previous year's wood.

Flowering period, May to July.

Veronica Prostrata.

PROSTRATE SPEEDWELL; _Nat. Ord._ SCROPHULARIACEÆ.

This is sometimes confounded with _V. repens_, I presume from the slight distinction in the specific names, but so different are the two species that no one who has seen them can possibly take one for the other. _V. repens_ is herb-like; it creeps and roots, and has nearly white flowers in April; but _V. prostrata_ is a deciduous trailer, and the more common and best form has fine gentian-blue flowers; it is a capital rock plant, being most effective when hanging over the face of large stones. The flowers are small, and produced in rather long sprays, which are numerous, so that little else than flowers can be seen for two or three weeks.

It will grow and flower freely in any soil, but the aspect should be sunny; it is easily increased by division or rootlets. I may add that the very long stems of this prostrate plant (when in bloom) are well adapted for indoor decoration. Where pendent, deep blue flowers are needed, there are very few good blues so suitable.

Flowering period, May to July.

Vesicaria Græca.

_Nat. Ord._ CRUCIFERÆ.

This beautiful, diminutive, hardy evergreen shrub comes to us from Switzerland, being an alpine species (see Fig. 109).

(One-third natural size; 1, full size.)]

When in flower it does not exceed the height of 6in. or 8in., at which time it is very showy, covered, as it is, with flowers of the brightest golden yellow, surpassing the golden alyssum, which in some respects it resembles, being half woody, possessing greyish leaves, and dense heads of flowers, which, however, are arranged in small corymbs, and being also much larger. The leaves of the flower stalks resemble lavender leaves in general appearance; those of the unproductive stems are larger, and arranged sparingly in rigid rosette form, such unproductive stems being few.

The neat and erect habit of the plant renders it most suitable for rockwork or edgings, and otherwise, from its long continued flowering, which will exceed a month in moderate weather, it is one of the most useful spring flowers; whilst, for cutting purposes, it cannot but rank with the more choice, as, combined with extra brightness of colour, it exhales a rich hawthorn perfume. To all who have a garden, big or little, I would say, grow this sweet little shrub. It has never failed to do well with me in any situation that was fully exposed; it flowers freely in a light dry bed, but on rockwork it is most at home. The quickest way to prepare plants of flowering strength is to divide strong pieces; but this interferes with the larger specimens, which are by far the best forms in which to grow and retain it. Another mode is to cut off all the flowers nearly down to the old wood; side shoots will thus be induced to grow earlier than otherwise, so that in late summer they may be taken off as slips, and there will still be plenty of time to strike them like wallflower slips, and get plenty of roots to them before the cold weather sets in. The plant also produces seed freely in its inflated pods, which affords another, but more tedious, way of increasing it.

Flowering period, April to June.

Viola Pedata.

PEDATE-LEAVED _or_ BIRD'S-FOOT VIOLET; _Nat. Ord._ VIOLACEÆ.

Over a hundred years ago this hardy herbaceous violet was introduced from North America; still, it is not largely grown, though it is now becoming quite a favourite. As may be seen by the illustration (Fig. 110), it is distinct in general appearance, more especially in the foliage, which in its young state is bird-foot-shaped, whence the appropriateness of its specific name; it should perhaps be explained that the leaves are very small compared with the flowers when the plant first begins to bloom, but later they increase very much in size. There are several characteristics about this species which render it desirable, and no choice collection should be without either this (the typical form) or some of its varieties. Deep cut, shining, dark green foliage, very bright blue flowers, and pleasing habit are its most prominent features; its blooming period is prolonged, and it has a robust constitution, which further commends it to lovers of choice flowers, and if once planted in proper quarters it gives no further trouble in the way of treatment.

The flowers are nearly an inch across, bright purple-blue, produced on stalks of varying lengths, but mostly long; the leaves are many parted, segments long, narrow and lance-shaped, some being cut or toothed near the tips; the crown of the root is rather bulky; the roots are long and fleshy.

The following are varieties; all are handsome and worth growing: _V. p. alba_, new; flowers white, not so robust as the type. _V. p. bicolor_, new; flowers two colours. _V. p. flabellata_ (syn. _V. digitata_); flowers light purple. _V. p. ranunculifolia_ (syn. _V. ranunculifolia_); flowers nearly white.

(Two-thirds natural size.)]

As this plant requires a moist and partially shaded situation, it is not eligible for doing duty indiscriminately in any part of the garden; still, it will thrive under any conditions such as the well-known violets are seen to encounter. On the north or west side of rockwork, in dips or moist parts, it will be found to do well and prove attractive.

The propagation of all the kinds may be carried out by allowing the seed to scatter itself, and, before the winter sets in, a light top-dressing of half rotted leaves and sand will not only be a natural way of protecting it until germination takes place, but will also be of much benefit to the parent plants. Another mode of increase is to divide the roots of strong and healthy specimens; in this way only can true kinds be obtained; seedlings are almost certain to be crossed.

Flowering period, May and June.

Viola Tricolor.

THREE-COLOURED VIOLET, PANSY, or HEARTSEASE; _Nat. Ord._ VIOLACEÆ.

(One-third natural size.)]

This well known herbaceous perennial is a British species. It has long been grown in gardens, where, by selection and crossing, innumerable and beautiful kinds have been produced, so that at the present time it is not only a "florist's flower," but a general favourite. Besides the above-mentioned common names, it has many others, and it may not be uninteresting to repeat them--"Love in Idleness," "Call me to you," "Kiss me ere I rise," "Herb Trinity," and "Three Faces under one Hood." Although this plant is herbaceous, the old stems remain green until the new growths come into flower, and, in many varieties, by a little management in plucking out the buds during summer, flowers may be had in the autumn and well into winter. If, also, from other plants early cuttings have been taken, and become well rooted, they will produce large flowers very early in spring, and so the Pansy may be had in flower nearly the year round. Any description of this well-known plant would be superfluous to an English reader.

The wild _V. tricolor_ is, however, a very different plant and flower to its numerous offspring, such as the illustration (Fig. 111) depicts, and in which there is ever a tendency to "go back." It is only by constant care and high cultivation that the Pansy is kept at such a high standard of excellence, and one may add that such labour is well repaid by the results. With no flower more than the Pansy does all depend on the propagation and culture. Not the least reliance can be placed on seeds for producing flowers like those of the parent. Cuttings or root divisions should be made in summer, so as to have them strong, to withstand the winter. They enjoy a stiffish loam, well enriched. And in spring they may be lifted with a ball and transplanted into beds, borders, lines, or irregular masses, where they are equally effective, and no flower is more reliable for a profusion of bloom.

Yucca Filamentosa.

THREADY-LEAVED YUCCA; _Nat. Ord._ LILIACEÆ.

This is of a more deciduous nature than _Y. gloriosa_, reclothing itself each spring more amply with foliage. In December, however, it is in fine form, and though it is a better flowering species than most of its genus, and to a fair extent valuable for its flowers, it will be more esteemed, perhaps, as a shrub of ornamental foliage. It came from Virginia in the year 1675.

The flowers are pretty, greenish-white, bell-shaped, and drooping: they are arranged in panicles, which, when sent up from strong plants, are, from their size, very attractive; but otherwise they are hardly up to the mark as flowers. The leaves in form are lance-shaped, concave, reflexed near the ends, and sharp-pointed. The colour is a yellowish-green, the edges are brown, and their substance is split up into curled filaments, which are sometimes 9in. or more long, and are blown about by every breeze. From these thready parts the species takes its name. It is seldom that this kind grows more than 4ft. high, but a greater number of offsets are produced from this than from any other of our cultivated Yuccas.

I know no better use for this kind than planting it on the knolly parts of rockwork, positions which in every way suit it, for it enjoys a warm, dry soil.

_Y. f. variegata_, as its name implies, is a form with coloured foliage. In the north it proves to be far from hardy, and therefore cannot be recommended for culture in the open garden. My reasons for mentioning it are that it is convenient to do so when the typical form is under notice, and that it is frequently spoken of as hardy. Subjects needing well selected positions, protection, and a mild winter in order to keep them alive from autumn to spring, can in no sense be considered hardy, even though they may be planted out of doors.

Flowering period, August to October.

Yucca Gloriosa.

GLORIOUS YUCCA, ADAM'S NEEDLE; _Nat. Ord._ LILIACEÆ.

A hardy evergreen shrub which has long been grown in England, but for all that is not often met with in private gardens. It is a native of South America, and was brought to our shores in 1596. The genus is remarkable for not flowering constantly in our climate, and also for slow growth; fortunately, both these drawbacks, if one may term them such, are counter-balanced by the handsome foliage of the various species, mostly of an evergreen and very durable nature, and also by the bold and symmetrical arrangement of the same. This Yucca flowers in the autumn, but it may be considered more especially a foliage subject, as the bloom is insignificant compared with the leaves and is not produced more than once in four years as a rule. The leaves assume their richest hues and become thoroughly matured about the end of the year; and when the ground is covered with a thick coat of snow, their rigid forms are amongst the very few of any note that can be seen. In any garden, no matter how large or how small, a Yucca imparts a style or character to it which scarcely any other subject can give. It may not be so easy to explain this, but the fact is recognised by the most casual observer at first sight. If I say the effect is tropical, noble, rich, and sometimes graceful, a partial idea of its ornamental qualities may be conveyed; but to know its value and enjoy it, it should be grown. The species under consideration has many forms, some differing rather widely from the type, so much so that these varieties are honoured with specific names. First may be given a brief description of the parent form.

It grows from 3ft. to 6ft. high, according to the more or less favourable conditions. These dimensions apply to blooming specimens; but shrubs, three to six years old, if they have never bloomed, may not exceed 1ft. to 2ft. in height, and about the same in diameter. The flowers, as may be gathered from the order to which the genus belongs, are lily-like, or bell-shaped; they are of a greenish white colour, arranged in lax clusters on stoutish stalks. The leaves are 12in. to 2ft. long, 3in. or more broad in their widest parts, concave or boat-shaped, sharp pointed, glaucous, sometimes slightly plicate, rigid, and leathery.

The habit, after flowering, is generally to form offsets, when the plant loses much of its former boldness and effect. From the lateness of its blooming period, and a lack of suitable conditions, it does not ripen seed in our climate, and it must of necessity be raised from seed ripened in more favourable climes.

The following are said to be some of its varieties, bearing useful descriptive names: _Y. g. pendula_, having a pendulous habit or reflexed leaves; _Y. g. plicata_, having plaited leaves; _Y. g. minor_, a lesser form in its various parts. There are other reputed varieties of more doubtful descent.

For cultivation see _Y. recurva_.

Yucca Recurva.

RECURVE-LEAVED YUCCA; _Common Name_, WEEPING YUCCA; _Nat. Ord._ LILIACEÆ.

This is a charming species, perfectly hardy and evergreen; it was brought from Georgia about ninety years ago.

The flowers are a greenish-white, and undesirable where the shrub is grown for the sake of its ornamental qualities; fortunately they are far from being constant in their appearance. September is its blooming period in our climate. The leaves are its main feature; with age it becomes rather tall, 6ft. to 9ft. high, having a woody hole or caudex, which is largely concealed by the handsome drooping foliage; a few of the youngest leaves from the middle of the tuft remain erect. The whole specimen is characterised by its deep green and glossy foliage, combined with a most graceful habit. Few things can be planted with such desirable effect as this shrub; it puts a stamp on the landscape, parterre and shrubland, and when well grown forms a landmark in the most extensive garden.

(one-eighteenth natural size.)]

For all the species and varieties of Yucca the mode of culture is not only similar but simple. They have long roots of a wiry texture. These denote that they require deep soil, light, and rather dry. Sandy loam, light vegetable soil, or marl and peat grow them well. Raised beds or borders, the higher parts of rockwork, or any open position, thoroughly drained, will not only be conducive to their health, but also prove fitting points of vantage. In planting Yuccas it must never be forgotten that perfect drainage is the all important requisite, and if it is not afforded the stock will never thrive, but ultimately die from rot or canker. Another matter, when referred to, will perhaps complete all that is special about the culture, or rather planting, of Yuccas. Begin with young stuff; I know nothing that transplants worse than this class of shrubs after they have become considerably grown. Their spare, wiry roots, when taken out of a sandy soil, do not carry a "ball," and from the great depth to which they run they are seldom taken up without more than ordinary damage. Young specimens, 6in., 9in., or not more than 12in. high, should be preferred, and of these sizes the least will prove the safest. Yuccas are readily propagated at the proper season; and in specifying the season it is needful to point out that of offsets, from which young stock is soonest obtained, there are two kinds. Some spring from immediately below the earth, and may more properly be termed suckers; the others grow on the visible part of the stem or caudex, often close to the oldest leaves; these should be cut off with a sharp knife, in early summer, and if they have a little of the parent bark attached to them all the better. If they are planted in a shady place, in sweet sandy loam, they will make good roots before winter, and may be allowed to make the following summer's growth in the same position. In the succeeding autumn it will be a good plan to put them in their permanent places. The suckers will be found to have more or less root; they should be taken in spring from the parent specimen, the roots should be carefully preserved, and the pushing parts planted just level with the surface.
